To aZZ whom it may concern:

Be it known that I, ORLANDO THoWLEss, of Newark, in the county of Essex and State of New Jersey, have invented certain new and -I then press the material by any convenient mode, and cut and make it up into bags of the sizes required.

To make my anti-tarnish solution I dissolve yellow prussiatc of potash (double cyanide of potash and iron) in hot water until no more will dissolve, and then dilute it with its own bulk of water containing a small amount of cyanide of potash-aboutaquarter of an ounce 25 to the gallon. When this solution is cold, and just before using, I add a small quantity of glycerine.

I am aware that paper and calico have been impregnated with oxide of zinc in a solution 0 of caustic soda for wrapping silver-ware to prevent its tarnishing, and this I do not claim; but

What I claim is 1. The anti-tarnish solution composed of 3 5 ferro-cyanide of potassium, cyanide of potassium,,and glycerine, substantially as and for the purpose specified.

2. As a new article of manufacture, a bag prepared and impregnated with ferro-cyanide 40 of potassium, cyanide of potassium, and glycerine, for the purpose set forth.

ORLANDO THOWLESS. Witnesses:
